The Family-Teaching Association certifies group homes in the use of evidence-based parenting methods. Everyone involved has to be trained and meet standards. These group homes have replaced what use to be call orphanages. A resident family-teaching couple has the role of parent for a group of kids. The organizations managing the group homes also provide support for troubled families as part of an overall system to deal with severe problems related to bad parenting.
So, at least, there is a licensing system geared to addressing the consequences of bad parenting.
Boy's Town is part of this system. It was an early adopter of evidence-based parenting that converted to family-like group homes in the 1970s. Perhaps a rare occasion when a religious organization was on the cutting edge of science.
Sir, Could I See Your Breeding License?
Most important is that children don't have to grow up under horrible circumstances inflicted on them by the inability of their parents. You always have to weigh the freedom of some against any negative infliction it could have on others. In this case a bit less freedom would guarantee a lot less distress.
It is reasonable. I don't see how we can ask for species-appropriate animal husbandry regarding animals like chimps but not children. You have to have a drivers license for good reasons too. So why is everyone allowed to rule over helpless human beings for years without having to prove their ability to do so in a way that guarantees the well-being of their protégé?
Such discussions always remind me about something important. Children should not be assigned with any religion. There should be a certain age where they can decide what religion they want to follow, if any. This doesn't mean that religious people shouldn't be able to have children but that they shouldn't be able to force their children into a certain framework either. Parents should be forced to allow their children to take part in a educational framework based on contemporary ethics and knowledge. I don't even have a problem with lessons in religion in school as it is part of human nature. But it shall not be focused on any truth value or a certain religion but an overview and comparison with non-religious ethics and truth-seeking.
